Be it known that l, CLAIR A. Nnsin'r, a citizen of the llnited States, residing at l `airburn, in the county of Custer and State n ot' iouth Dakota, have invented certain new and nse'ul improvements in Concrete Ties, of which the following; is a specication.V

rlhis invention relates more especially to a concrete tic and it has tor its primary obiii ject to provide a tie which will be ecn0mical in construction and may be readily manufactured at a cost favorable in comparison with the wooden tic. A I

rlhe invention further resides in a con-V crete tie having central as well'as lengthwise reinforcement. 1 Further, the invention resides in the ifeatuies or construction and thearrangements and combinations ot parts hereinafter described, reference being' made to the accompanyinp,` drawing wherein,

Figure l, is a perspective view of a concrete tie constructed in accordance with the present invention; Y f p Figure 2, is a fragmentary, longitudinal section therethrough; and

A"f ure 3 is a transverse central sectionA ci tie. f eferring more in detail to the accoinfing drawing, the concrete body l is l out at each end to pro-vide a tapered pexing'@ which entends inwardly to a point a jacent the center so as to leave a solid centrai portion 3 of considerable size. The tie is reinforced lengthwise by upper and lower series ol rods fr which extend substantially parallel to the adjacent tapering; wall of the opening 2. Consequently, the longitudinal reinforcing rods extend toward the longitudinal axis troni each end and each rod is therefore bowed, in eect, with the central portions oit the two seriesv being closer together than their extremities. portion 3 et the tie is also reinforced by a l' plurality of rows oi 'vertical rods or reinforcing' nienibers 5. This construction 'and arrangement ot the reiniforcingrods provides a tic that is effectively reinforced with particular attentionbeing given the central portion ot the tie, which portion has 1oeen found weak in concrete ties ci' former constructions.

Transversely across the topV of the tie are the rail seats 6 slin'htlv depressed to receive the bases of the rails. Each rail base is held rlfhe centrall e, 1923. serial no. 617,'237.

seated or in position by'a pair oi" anchor plates 7 disposed on opposite sides of the rail and overlappingV the base, said plates being secured inposition by a pair of bolts or a Ulbolt 8 which'is passed upwardly through a pair of vertical openings inthe tic. These openings lead irorn the tapered recesses 2 to the top surface of the Vtie and the tapered recesses are or suiiicient size to `permit the introduction of the U-bolts into the vertical openings. The free extremities of the U-bolts pass through the anchor plates and are threaded to receive the nuts 9. `Said anchor plates are provided with lugs lO'on their underiaces to fit in corresponding recessesV ll in the top surface of the tie to preventturning;` et the plates Vfrom-their operative position. Also a wooden block or cusliion'll is interposed between the base of each Lbolt and the upper .wall oil the respective tapered opening 2 to provide for yieldable orcushioning clamping of the rail as in the case ci? the woo-:len tie, the block l2 being` cut on the bias to conform said upper wall.

llVhat is claiined is:

l. A concrete tie comprisinc' a cenient body having a tapered openiu'ig` extending,T Vifroin each end beneath the rail-supporting portions and terminating` adjacentthe center so as to leave a central'solid portion.

2. fr concrete tie comprising a cement body having` a tapered opening extendingv :troni each end beneath the rail-supporting' portions and terrninating` adjacent the center so to leave a central solid portion, and areinlorceinent for the central portion.

3. concrete tic .comprising a cement body havinga tapered opening extendingiroin each end beneath the rail-supperting` yportions and terniinatingv adjacent the center so as to leave a central solid portion, ver- .tical reinforcing rods in the central. portion, andV longitudinal reiniforci'ng,r rods extending; the length oil the body.

il. tie comprisingv a concrete body haring end openings extending inwardly andv terminating* short oi the center to leave a central solid portion, and means leading.: Jfrom each opening. upwardly ior anchoring: a rail to the tie. Y

5L A tieconiprising a concrete body hav; ing end openings extending inwardly and terminating; short or" the center to leave a central solidportion, lengthwise reinforce ment for the body,transverse reinforcement gli through the openings upwardly through the body, means cooperating with the bolts for attaching rails to the tie, und cushion 10 Vmeans between the bases oi" the U-holt's und lthe upper walls of the openings of said tie. In testimony whereof I nihx 1n v snnnturc.
